Study of an External Responsive Neurostimulator System on Epileptiform Activity

2014-07-23 21:48:45 | BioPortfolio


This feasibility clinical investigation is designed to demonstrate that the NeuroPace external Responsive Neurostimulator (model eRNS-300) can safely deliver responsive electrical stimulation automatically to affect epileptiform activity. The eRNS-300 is based on an implantable neurostimulator that has been adapted for acute, external use in a hospital setting.


The Automated Response to Spontaneous Epileptiform Activity using the External Responsive Neurostimulator (eRNS) system clinical investigation involves subjects who are undergoing intracranial monitoring for the evaluation of epilepsy surgery and who are being monitored in the hospital's epilepsy monitoring unit. During the subject's participation, at the discretion of the investigator, the subject will be connected to the eRNS. The eRNS is an investigational device that attaches to standard intracranial electrode monitoring equipment to monitor the subject's seizure activity. It is anticipated that the subject may be connected to the eRNS for a period of time extending from one day to a few weeks. After the subject has enough seizures to complete their evaluation for epilepsy surgery, the physician may enable the responsive stimulation settings for the eRNS. The subject's participation in the clinical investigation will be complete prior to the removal of their intracranial electrodes.

The outer part of the hearing system of the body. It includes the shell-like EAR AURICLE which collects sound, and the EXTERNAL EAR CANAL, the TYMPANIC MEMBRANE, and the EXTERNAL EAR CARTILAGES.

A disorder characterized by the onset of myoclonus in adolescence, a marked increase in the incidence of absence seizures (see EPILEPSY, ABSENCE), and generalized major motor seizures (see EPILEPSY, TONIC-CLONIC). The myoclonic episodes tend to occur shortly after awakening. Seizures tend to be aggravated by sleep deprivation and alcohol consumption. Hereditary and sporadic forms have been identified. (From Adams et al., Principles of Neurology, 6th ed, p323)

A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)

Signal transduction mechanisms whereby calcium mobilization (from outside the cell or from intracellular storage pools) to the cytoplasm is triggered by external stimuli. Calcium signals are often seen to propagate as waves, oscillations, spikes, sparks, or puffs. The calcium acts as an intracellular messenger by activating calcium-responsive proteins.

Antineoplastic agents that are used to treat hormone-sensitive tumors. Hormone-sensitive tumors may be hormone-dependent, hormone-responsive, or both. A hormone-dependent tumor regresses on removal of the hormonal stimulus, by surgery or pharmacological block. Hormone-responsive tumors may regress when pharmacologic amounts of hormones are administered regardless of whether previous signs of hormone sensitivity were observed. The major hormone-responsive cancers include carcinomas of the breast, prostate, and endometrium; lymphomas; and certain leukemias. (From AMA Drug Evaluations Annual 1994, p2079)
